hi, I can't login normally so I am going to answer this as a guest. If it is just water and not coolant I would check your heater plenum drain. You get condensation when ever the AC is turned on. (AC is turned on automatically is you turn on defrost) There is a drain to allow the water from condensation to drain out underneath the passenger side of the vehicle. Sometimes dust gets mixed with the water and when it dries it plugs the drain tube. With the drain plugged it will fill up in the plenum and start to leak inside the car. Try to find the drain and see if you can unplug it.
If you have a leak in the heater core or a leak in a heater hose that connects to the heater core they would leak coolant into the heater plenum. If the liquid is not coolant then it should be the AC condensation.
